TALKING-MACHINE.

Specification of Letters Patent.

Patented Get. 17. 191 i;

Application filed December 3, 1906. Serial No. 346,026.

To all whom it may concern:

Be it known that I, WALTER H. Polo runny, a citizen of the UnitedStates, resid ing .at New York city, borough of Mom .5 huttan, in thecounty and State of New York,

have invented certain new and useful linprove nents in Talking-Machines,oil" which the following is a specification.

My invention relates generally to talking n'istically controlling therotating table or support which carries the record.

Tho object of the invention is to do away with the hand-operated brakenew commonly employed. in talking machines and cause the rotation of therecord supporting table to be automatically controlled by the sound-boxor reproducer, which, in being lowered into engagement with the recordor swung upward clear of the seine, aotuetes it suitable brake device ine manner to limit thQ l'otation eof the record supporting table toperiods When the reprodueer is in contact with the record.

irfurther object is to utilize the brake {LS inc-inns of yicldinglysupporting the soundz in. the position it usually occupies shove clearof the record when the machine is not in operation or while one recordis being sostituted for another.

Mechanism suitable for curryi 4 my inion into eilect is illustrated inthe acing drawings. i do not wish to be is cod, howeyer, as limitingmyself "to the exact Hl'fi or arm. hown, as r; ions clmng ther inwithout dopurti -.1 and sipe of my invention.

fie rhwm ings-l igure 1 is a side clepurily in section, of talking me. owell known type, showing my Fig. 2 is ndoteil. cross only be from the a.detail section on the line e, s", and Fig. 5 is a like new on the l 3 ofFig. l.

' ierring now to, the drawings, '1. repre-.

sents the casing of the nuichine, the retating table on which the record3 is supported, 4- a bracket secured to the casing and provided with nvertically disposed sleevelike ofi' set 5, to receive the small end ofthe horn 6 ,andlthe shaped end of, the tapered arm or sound. conveyingtube 7 The sleeve machines and particularly to means for auto seen thatus the sound-Mix is slotted upon opposite sides as indicated at S andprojecting into the slots, there are oppositely disposed screws or studs9,3vhieh serve to secure the tapererin in position and support the somefree to swing vertically and horizontally. At the outer end of the arm7, n. sound-box 10 is mounted in the usual manner to cooperate with therecord carried by the rotating table above refe red to, the arm 7 andsound-box 10 forming the reprorilucer. t i The construction thus fardescribed is that found in machines now in general use and forms no partof tile present invention, being here employed for purposes of illustro.tio'n only and it will he understood that the invention is not limitedin its use to the particular type of machine shown.

Pivotelly mounted upon a. cross pin ll of the bracket 4, there is ahrnkenrin 12, the free end of whieh is recessed to receive a. piece offelt or other material suitable for tricrionelly engaging the edge ofthe rotat-- ing table.

Under the notion of twin springs 1.3, orrnnged one on each sideofthe arm12, as shown in i ig. 3, the brake yicldingly held llher in or out ofengagement \Yllll the table. The springs are secured at their owor endston cross pin i l, fixed directly elow the piyot pin and have theirupper c;.ds hooked over uds l1) ot the lu'ukcnrni, the arrangement beingsuch, that as the brake-arm moved for enough in either allrectiontoirnrry the studs over the pivotal center, the springs not to contimicthe movemontnand snup the brake forward into on gogcinont with the tableor backward against a stop 16, depending u mntho direction of theinitial l'i'lUYQlllOiiil iuipmrted to the some.

The brake connected i'h ough a link 17, hell-crunk l5 and pin 1?), tothe elbow of the taper arm and tlu'is :urruu bl, it will he tilledi'roo'i the record, motion will he in'iported through the coiuiei'ztion.described, to the brake-uric, giving it movement :l'orwar d toward thetable until the studs 15 pass over the pivotnl center 14 and thereupon,the springs not to complete the movement and yieldingly maintain thebrake applied.

It will be observed, that when the brake is thrown on as just described,the return of the sound-hox is opposed by the brake springs and as a.result, the sound-bcx is vieldingly held by the same in an elevatedrotation of the support.

locking device such as is ordinarily employed for this purpose.

To throw off the brake, it is only necessary to move the sound-boxdownward toward the record and the required motion will be imparted tocause the brake-arm to swing away from the table until the springs actto force it back against the stop.

A pin and slot connection indicated at 20, is preferably employedbetween the bellcrank and the link 17, in order to produce sutlicientlost motion to enable the brake to be thrown on or oli' at any desiredpoint in the vertical movement of the sound-box.

The pin 19 is connected to the taper arm by a universal joint indicatedat 21, which permits the arm to mo've freely both vertically andhorizontally as required.

In adapting the device to other types of talking machines, theconnection between the taper arm and the brake may be changed in anymanner desired or the brake may be arranged to cooperate with somemember of the motor other than the rotating table or other changes maybe made in the construction shown within the meaning of the presentinvention, the essential feature of which is the automatic control ofthe brake by the sound-box, the resulting advantages of which will beapparent from the foregoing description.

Having. therefore, described my invention, I claim:

1.
